Very common trope in 50's sci-fi and horror posters, the attractive damsel in distress often appeared in the arms of her predator or savior, with her tight dress and helpless pose.
There are a bunch of other similar posters that feature the pretty woman, in a dress, lied down looking frightened. But I've tried to put only the ones that the woman is in someone's arms someway. I've found so many posters like this that I got tired of searching.
Ps: I know Black Orpheus has nothing to do with it, but it's a nice poster that follows the pattern, so I put it there.
